What Happens During a Chiropractic Adjustment?

This is the question we're asked more than any other, usually by people who've seen a video of someone being adjusted and found it alarming.

An adjustment is a controlled movement applied to one specific joint that isn't moving as it should. It takes a fraction of a second and involves considerably less force than most people expect. In a treatment room it's undramatic, and we'll talk you through it before we do anything.

Here's what actually happens, what the popping sound is, whether it hurts, and how you're likely to feel afterwards.

What we're doing

We take a joint just past its everyday range of movement, and nowhere near its anatomical limit. The direction, depth and speed are all deliberate.

The aim is to restore movement to a joint that has become stiff and painful, and to reduce the pain associated with it.

The popping sound

It's called cavitation, and it has nothing to do with your bones.

Joints sit inside capsules containing fluid, and that fluid holds dissolved gas. When the joint surfaces separate quickly, the pressure drops and gas comes out of solution. That's the sound.

Two things follow from this.

Nothing is going back into place, because nothing was out of place. The noise isn't evidence that anything has been corrected.

And a silent adjustment isn't a failed one. Plenty of effective treatment makes no sound at all. What matters is how the joint moves afterwards, not what you heard.

Step by step

Positioning. You'll be on the treatment table, face down, on your side, or on your back depending on the area. Getting this right is most of the technique.

Contact. We find the specific joint we're treating.

Taking up the slack. We take the joint gently to the end of its comfortable range. For most people this is the most noticeable part.

The thrust. Quick and shallow, and usually over before you've registered it starting.

Reassessment. We retest the movement immediately to see what's changed.

Two or three joints in a session is typical, not a run down the whole spine.

Does it hurt?

Usually not. Most people describe pressure, or a sensation that's unfamiliar rather than painful.

Where there's inflammation or the muscles are guarding, it can be briefly uncomfortable. Tell us if it is.

If you're tense about it, say so. Tensing up makes an adjustment harder to perform well, so we'd rather slow down and explain what we're about to do.

You can also decline. If you'd prefer we didn't adjust your neck, tell us at the start. There's more than one way to treat a neck and it's a normal request.

What else happens in a session

Adjustments rarely appear on their own. Depending on your presentation, we may also use soft tissue and deep tissue work, joint mobilisation (the same principle applied slowly, without a thrust), dry needling, or cupping, along with exercises to take home.

If manipulation isn't suitable for you, mobilisation and soft tissue work cover much of the same ground. Nobody has to have an adjustment.

If thrust techniques aren't appropriate

Some people aren't good candidates. Reduced bone density, certain inflammatory conditions, or simply finding the technique too confronting are all valid reasons.

Lower-force options include instrument-assisted adjusting and drop-piece tables, alongside mobilisation. These are legitimate techniques in their own right, not a lesser version of treatment.

How you'll feel afterwards

Most people notice easier movement fairly quickly. Some feel immediate relief. Others feel little at the time and better the following morning.

Mild soreness is common, particularly after a first session. It's comparable to the stiffness after unfamiliar exercise, typically starting within a few hours and settling within a day or two. Normal movement helps, and most people find heat more comfortable than ice.

Occasionally people feel briefly tired or lightheaded. Sit for a minute before driving if that happens.

What we don't expect is severe pain, new numbness or weakness, or a significant headache. If any of those occur, contact us or seek medical advice. We've covered this in is chiropractic treatment safe.

Will you adjust me every visit?

Not necessarily, and it isn't a measure of progress.

As a joint begins moving better, treatment usually shifts toward exercise and loading, because that's what makes the improvement last. If you're several weeks in and your care still consists only of adjustments with no change in your symptoms, raise it with your practitioner.

Before your first appointment

Wear clothes you can move in, arrive a few minutes early, and bring any scans. Full checklist here: what to do before your first chiropractic appointment.
